Uncle John was in the fertilized egg business. 
He had several hundred young layers, called pullets,
 and 8 or 10 roosters  whose job was to fertilize the eggs. 

My uncle kept records, and any rooster or pullet that 
didn't perform well went into the pot and was replaced. 

This took a lot of time. 

So, my uncle got a set of tiny bells and attached them to 
his roosters. He could then sit on the porch and fill out 
an efficiency report by listening to the bells. 

My uncle's favorite was Brewster Rooster. A very fine 
specimen he  was, but his bell had not rung 
all morning, so Uncle John went to investigate. 

Several roosters were chasing pullets, bells a-ringing. 
Brewster had  his bell in his beak so it couldn't ring. 
He'd sneak up on a pullet, do  his job and walk on 
to the next one. 

Uncle was so proud of Brewster he entered him in 
the county fair, and he was an overnight sensation. 

 Now here it comes 

The judges not only awarded him the No Bell Prize, 
but also the Pullet Surprise.
